1 Claim, 3 Drawing Figures AIR SEAT This invention relates generally tocushions.

A principal object of the present invention is to provide an air seatwhich is adaptable for placement upon a hard seat or bench or whichmaybe placed upon the ground so as to give a person greater comfortusing the same.

Another object of the present invention is to provide an air seat whichaccordingly is ideal for use at baseball games and other events wherepersons are usually obliged to sit upon a hard bench or the like, orwhich alternately can be used by fishermen or campers who are oftenobliged to sit upon the ground or upon a hard rock when out of doors.

Still another object of the present invention is to provide an air seatwhich in a deflated position can be readily folded up so to take up aminimum amount of space and thus be conveniently and easily transported.

Still another object of the present invention is to provide an air seatwhich can be quickly and easily inflated by a person for operative useand which does not require any specialpumps but which can be inflated bysimply a person blowing there into.

Other objects of the present invention are to provide an air seat whichis simple in design, inexpensive to manufacture, rugged in construction,easy to use and efficient in operation.

These and other objects will be readily evident upon a study of thefollowing specification and the accompanying drawing wherein:

FIG. 1 is a perspective view of the present invention,

FIG. 2 is a cross sectional view taken on the line 22 of FIG. 1, and

FIG. 3 is a bottom plan view of the air cushion.

Referring now to the drawing in detail, the reference numeral representsan air cushion according to the present invention wherein there is aseat member and a back rest member, the seat member being defined by thereference numeral 11 and the back rest member being defined by thereference numeral 12.

The seat and the back rest are made integral and are foldable respectiveto each other about a bend or fold line 13 so that they may assume theposition as shown in FIG. 1 or alternately they maybe folded back toback so that they maybe used only as a seat. Altemately they maybe laidout flat upon a ground so that two persons maybe seated there upon.

The seat 11 and the back rest 12 are each formed of a series ofparallel, spaced apart inflatable tubes 14 which are spaced apart fromeach other by means of webs 15, each of the webs 15 being provided witha series of ventilation openings 16 there through so to give comfortduring hot weather and allow a person to remain cool withoutperspiration remaining clinging to him.

The material used in the construction of the air seat may comprise thesame material as is used in the construction of a good quality airmattress and is then covered with a nylon material. Accordingly thematerial is air proof so to prevent leakage of air there through. An airvalve 17 inflatable by oral means is attached to each of the seal andback rest as shown in FIG. 1 so to permit air to be placed into thetubes or removed there from. The tubes of the seat and the tubes of theback rest maybe interconnected together so that only one air valve 17maybe necessary as shown. The air valve 17 may be located along theedges of the seat and the back rest where they are out of the way sothat a person does not lean against them when using the air seat.

It is to be noted that the air seat when inflated is floatable so thatit would be particularly adaptable also for use on pleasure boats andwhich could be used as an emergency life saver by throwing it to aperson in need in the water. Alternately the air seat by being floatablewould not become lost if dropped in the water. Additionally the devicemight be adaptable for use in a swimming pool.

Thus there is provided an air seat providing advantages for a person whootherwise would be obliged to sit upon a hard surface.

What I now claim is:

1. In an air seat, the combination of a seat member and a back restmember, said seat member and said back rest member being attachedpivotally together along a fold line, said seat member and said backrest member accordingly being adaptable for use in various respectivepositions to each other as preferred so that in one situation said seatmember can be placed upon a hard bench or ground while said back rest isreclined in upstanding position against a supporting surface, and in analternate position both said members maybe in a horizontal position forplacement upon a hard surface so that two persons may be seatedthereupon or one person reclined thereupon, said seat member and saidback rest member being each formed of an air tight material andfashioned into a plurality of parallel, spacedapart tubes within whichair can be inflated or removed therefrom, and a web being locatedbetween said tube, said web each being provided with a plurality ofventilation openings therethrough, said web being wider than a diameterof said openings, said air tubes being inflatable or defiatable by meansof an air valve located along an edge of said seat and said back rest.
